  • Diatoms dominate the biomass of phytoplankton in nutrient-rich conditions and form the basis of some of the world’s most productive marine food webs. The diatom nuclear genome contains genes with bacterial and plastid origins as well as genes of the secondary endosymbiotic host (the exosymbiont), yet little is known about the relative contribution of each gene group to diatom metabolism. Here we show that the exosymbiont-derived ornithine-urea cycle, which is similar to that of metazoans but is… CONTINUE READING
